AIR GUN.

Application filed September 21, 1925.

The invention relates to air guns of the repeating type having a magazine for bold.- ing the shot and a feed mechanism for mtroducing the same into the barrel. In guns of this type it is common to provide a detachable barrel within the outer casing or magazine, the latter having a loading aperture therein which is closed by a member carried by said barrel. When the barrel is threadedly secured to said casing and is screwed tightly against the cooperating member it sometimes happens that the clo sure is not in exact alignment with the loading aperture, thus permitting the shot in the magazine to fall out of the gun. .Vhile this trouble may be remedied by slightly unscrewing the barrel until the closure registers with the magazine aperture it is not always understood by the children using the gun, thus causing annoyance and dissatisfaction.

One of the objects of my invention is to provide an arrangement for overcoming the defect above referred to and this has been accomplished by securing the barrel to the gun in such a manner as to permit unlimlted rotation of the barrel without axial movement after it has been secured in axial position by threaded engagement. Another object is to provice an improved construction of abutment for receiving the inner end ot the barrel and securing the same to the outer casing.

in the drawings:

Figure 1 is a side elevation of an air gun;

Figure 2 is a longitudinal section through a portion of the gun barrel;

, Figure 3 is an enlarged view illustrating the engagement of barrel and abutment;

Figure d is a sectional view of the abutment;

Figure 5 is an end view thereof.

A represents the air gun as a whole provided with the usual operating mechanism for propelling the shot, this mechanism not being specifically illustrated. since it forms no part 01": the present invention. B is the outer casing o'r so-called false barrel which forms the magazine C for the shot and is provided at its outer and upper portion with a loading aperture D. E is the inner tube or true barrel extending within the outer casing and having at its outer end the clo- Serial No. 57,686.

sure F adapted to engage the outer casing to close the magazine. The inner end of the barrel E has secured thereto a member G having external threads H, an annular flange I and a cut-away portion J intermediate the threads and said flange. K is a feeding mechanism for introducing the shot one at a time into the barrel E through the aperture L.

For engaging the threaded end of the barrel E there is provided an abutment comprising :1v sheet metal tube M preferably formed from a flatsheet and provided with a longitudinal slot N between the adjacent edges. The tube is permanently secured within the outer casing B by spot-welding or other suitable means and is provided at its forward end with a nut 0 having a cylindrical outer surface P sleeved within said tube and having an annular flange Q engaging the end of said tube. he flange has two or more apertures R therein for receiving the ears S which project from the tube M. the latter being bent inward as indicated at T to secure the nut to the tube. The nut O is provided with a threaded aperture U adapted to engage the threads H and is also provided with the enlarged recess V for receiving the threads H when the barrel is threaded through the aperture U.

l Vith this construction, the barrel E is secured to outer casing by the threaded engagement 0r portions H and U, thus drawthe closure F into engagen'ient with the outer casing. Further rotation 01": the barrel E allows the threaded portion H to engage in the enlarged recess V and the threaded portion U to engage in the cut-away portion, J, thus permitting relative rotation of the parts without further axial movement. The flanges I and Q, prevent further axial movement inward while the threaded port-ions H and U prevent axial movement outward without corresponding rotation.

The closure member F has secured there to, the spring arm having a detent X for engaging and closing the loading aperture D when the aperture L is in its upper position. It will be readily apparent therefore, that the threading of the barrel E into en gagement with the abutment draws the detent X into longitudinal alignment with the aperture D, while the radial registration will be obtained by further rotation of the barrel Without corresponding axial movement.

What I claim as my invention is 1. In a gun, the combination with a tubular outer casingsimulating a barrel and formed with a loading aperture, of an abutment secured Within said casing "formed vith a threaded opening, a tube within said casing forming the true barrel for said gun and having a threaded'portion adapted to be screwed into and east the threads of said opening, a closure for said loading aperture carried-by said tube, said closure being; re aered with the plz-tne of the load ing aperture transverse to the barrel by threading the barrel through said opening;

of the abutment, saidtuhe being 'l'reeljv rotutablerelatwe to the abutment when its threads having been screwed. past these of the abutment to engage said closure with said loading aperture.

In a gun, the combination with an outer tubular casing sin'iulating a barrel and formed with a loading aperture, of an abut ment within said barrel having an aperture therethrough, a tube Within said barrel having an end portion retained in said opening and rotatable Within the barrel in .l fixed longitudinal relation to the barrel, and a closure mounted upon said tube and engageable with and disengaggeable from said loading aperture by rotation oi the tube.

In a gun, the combination with an outer casing, of a removable barrel Within said casing forming therebetiveen a magazine and havinga threaded inner end, athreaded abutmenton said casing for engaging'said threaded end, oneotsaid threaded members having a cutaway portion adapted to engage the threaded portion of the other member to permit relative rotation of said members Without axial movement, and cooperating :diutments on the respective threaded me i bers for limiting Xltll movement in one direction.

-.l-. in a gun, the combination with a tubular easing simulating a barrel, provided with a tl railed abutment therein, said casino forming a. magazine and having a loadi aperture therein, a tube Within said casing}; forming the true barrel "for said gun and having a threaded portion for engaging; said threaded abutment, a closure for the end of said casing secured to said tube, means carried by said tube for closing said loadingaperture, and a cut-away portion on one of said threaded'inembers adapted to engage the threaded portion of the other member after a predetermined threaded engagement of said members whereby said tube and closing means may be rotated Without axial movement.

5. in a gun, the combination with a tubular casin -simulating a barrel provided with a threaded abutment therein, said casing forming a magazine havinga loading apcrture therein, a tube Within said casing t'orming the true barrel and having a threaded portion for enga ing said threaded abutment, a closure for the end of said tubular casing secured to said inner tube, spring detent carriedby said closure adapted to" engage said loading aperture when said tube iallv and 'rotatably aligned therewith.- cutaway portions on said tube and said abutment arranged adjacent to the respective tl'i'readed portions thereof, nch of said cutaway portions being adapted to receive the threaded portion of the other nember i'njedetermined threaded engagement there of to permit rotation of said'tube Without az-t'al movement thereof, and cooperating surfaces on said tube and abutment for limiting axial movenient in one direction.
